no. They're not. Japanese people are just really good at hiding how they really feel. Its cultural.
Ive been to Tokyo multiple times, and spent significant time there. They're generally a$$holes to nonwhite foreigners, and even some white foreigners. There are bars and restaurants that don't allow non-Japanese people in, period.
Tokyo has a nice face in the front but don't get it twisted, it has a dark side like every city.
I got robbed in Tokyo.
Still, overall a cool place with plenty to do. I gave it an 8 because its so fukking expensive, even just to get from one station to another. And well, I've seen how shytty Japanese people can really be. If you only spend a few days there, I can see why you'd give it a 10.
